GARY NUNEZ & PLENA LIBRE/Corazon: Oh, the things the average gringo doesn't know about Puerto Rican music. He probably can't tell the difference between this and the third world party music in "Romancing the Stone". He probably doesn't know Tito Puente was Puerto Rican. He still wants to know why the Sharks dance so much when they rumble. But--he does know the difference between good music and bad. He does know which kind of Latin music encourages breaking out the cerveza. And he knows which music will let him adapt the white guy dance to the Steve Martin mambo so he can shut his uptight, white, honky chica up and dance occasionally without feeling clumsy and gay. Hold your stomach with one hand, point with the other. Sway your hips and shuffle your feet. This is great white guy/Steve Martin mambo dance music. And best of all, you can tell her you tried. Nunez and his pals are doing more for pan cultural relations than they realize with their pan Caribbean genre splicing. This is a ticket to having her let you enjoy the Super Bowl and the play offs because at least you tried. Guys everywhere want Nunez for President.
